Abstract
Flexural tests on X7/5 wire prestressed concrete beams made with High Alumina Cement (HAC) are described. The beams were artificially converted (in the range 10–100±5%) and observations were made on central deflection, strains, ultrasonic pulse velocities, cube compressive and prism flexural strengths, and concrete moduli.
Although the conversion caused some major changes in the concrete properties the effect on the ultimate moment capacity of the beams was minor, due to the under-reinforced nature of this particular section at these particular concrete strengths.
